Can you describe this in more detail? When you clear the screen, it
should simply be empty afterwards with no possible chance of flickering,
unless...

... you do this on e.g. a shell prompt, which usually would result in
the shell redrawing the prompt after clearing the screen fully.

Then likely what you describe as flickering is simply due to urxvt being
faster than the other terminals you are using, i.e. urxvt shows you a clear
screen followed by your prompt, which would mean urxvt is not flickering, but
your shell is.

A simple workaround for your example would be to not keep rpessing ctrl-l,
of course :)

You would probably need to run a program that doesn't flicker - urxvt
simply shows what it's told to and wouldn't be the cause of the flickering
itself (and can't really do anything about it).
